How do mosquitoes find love? Turns out, they serenade their mates! Scientists at Cornell University found out by supergluing mosquitoes on to a tiny tether and then suspending them in the air:

The male mosquito's buzz, or flight tone, is normally about 600 cycles per second, or 600-Hz. The female's tone is about 400-Hz. In music, he's roughly a D, and she's about a G. So the male brings his tone into phase with the female's to create a near-perfect duet. Together, the two tones create what musicians call an overtone — a third, fainter tone at 1200-Hz. Only then will the mosquitoes mate.
